[Electrophoretic characterization of hemoglobin in rats at different ages]

Under conditions of electrophoresis in polyacrylamide gel hemoglobin dissolved in 0.1% solution of NaCl is divided into two components. In old rats the amount of a "slow" component increases. When stored in vitro the whole "quick" component is converted into a "slow" one, however in the former case the process is accompanied by a simultaneous decrease in the ratio between SH- and S--S-groups, in the latter case such phenomenon is absent.
